Question 9
Magnification produced by a rear view mirror fitted in vehicles

(a) is less than one
(b) is more than one
(c) is equal to one
(d) can be more than or less than one depending upon the position of the object in front of it .

Answer 1

(a) is less than one

Images formed by a rear view mirror are diminished i.e. $h_i<h_o$.
Magnification, $m=\frac{h_i}{h_o}$
$\Rightarrow$ Magnification, $m<1$
$\therefore$ Magnification produced by a rear view mirror fitted in vehicles is less than unity.
